Locations of mines and prospects in Amelia County, Virginia

Critical minerals are essential for the energy transition; to meet sustainability goals, production of these resources must significantly increase within the coming decades. For example, demand for lithium, an element essential for battery technologies found in many electronics and vehicles, is anticipated to increase by more than ten-fold by 2050 compared to current production. Critical minerals

Grade and tonnage data for tungsten vein and greisen deposits

Tungsten is a mineral commodity critical for national security and the economy. Vein and greisen deposits host wolframite, a tungsten ore mineral that accounts for a significant portion of global mine production and resources. This data release contains updated resource information for globally distributed deposits that underpin grade and tonnage modeling efforts.

Geoheritage Sites of the Nation Data Release v.1

Geoheritage is a term which lies at the intersection of science, society, and sustainability and is applied to significant geologic features and landforms that have scientific, educational, cultural, economic, and aesthetic value. Many geologic sites have enriched society through the geoheritage values: scientific research and education, cultural significance, economic opportunities, and aesthetic

Pre-mining environmental baseline characterization of the Nuqra Khana iron deposit: 2020 field season

These data include geochemical analyses of rock, soil, sediment, and water samples collected from the Nuqra Khana iron deposit, Panjshir Province, Afghanistan in 2020.

Pre-mining environmental baseline characterization of the Balkhab copper deposit: 2020 field season

These data include geochemical analyses of rock, mine waste, and water samples collected from the Balkhab copper deposit, Sar-e Pol Province, Afghanistan in 2020.

Yukon-Tanana Upland airborne magnetic geophysical data merge, version 2023

The Yukon-Tanana Upland airborne magnetic geophysical data merge provides a merged raster grid of magnetic data for the Yukon-Tanana Upland (YTU), Alaska. This dataset provides a regionally consistent magnetic grid while retaining as much detail as possible of the originating data by leveling all the region's magnetic grids to one another. This 100-m cell-size magnetic grid of the YTU will assist

Lithium observations, machine-learning predictions, and mass estimates from the Smackover Formation brines in southern Arkansas

Global demand for lithium, the primary component of lithium-ion batteries, greatly exceeds known supplies and this imbalance is expected to increase as the world transitions away from fossil fuel energy sources. The goal of this work was to calculate the total lithium mass in brines of the Reynolds oolite unit of the Smackover Formation in southern Arkansas using predicted lithium concentrations f

Carbon Dioxide Storage Resources-Anadarko and Southern Oklahoma Basins: Chapter R. Spatial Data

This data release provides shapefiles that represent storage assessment units (SAUs) and drilling-density cells in the Anadarko and Southern Oklahoma Basins of Colorado, Kansas, Oklahoma, and Texas in the United States. The SAU is the fundamental unit used in the National Assessment of Geologic Carbon Dioxide Storage Resources project for the assessment of geologic CO2 storage resources. The SAU i

Reflectance data from figures in: Using X-ray spectrum of carbon in electron microprobe analysis to determine thermal maturity of organic matter in mudstones

Conventional methods of assessing organic matter (OM) thermal maturity have limitations and often fail to reflect the geochemical heterogeneity between individual organic phases in mudstone samples. Vitrinite and solid bitumen reflectance, for example, is often measured to estimate OM thermal maturity but is restricted to specific types of OM. Alternative methods deserve exploration. This dataset

Pre-mining environmental baseline characterization of the Hajigak iron deposit: 2020 field season

These data include geochemical analyses of rock and water samples collected from the Hajigak iron deposit, Bamyan and Wardak Provinces, Afghanistan in 2020.

Pre-mining environmental baseline characterization of the Aynak copper deposit: 2020 field season

These data include geochemical analyses of rock, mine waste, and water samples collected from the Aynak copper deposit, Logar Province, Afghanistan in 2020.

Evaluation of solid bitumen created from marine oil shale bituminite under hydrous and anhydrous pyrolysis conditions

This study tests the influence of environmental conditions on conversion of the maceral bituminite to a solid petroleum residuum (solid bitumen) during pyrolysis. The presence of water in sedimentary basins controls multiple processes during petroleum generation, migration, and storage. Four organic-rich (26–36 wt.% total organic carbon) oil shale samples were collected from thin-bedded (several c
